This article introduces the knowledge of "how to use Scale controls to control the size and color of label fonts". In the operation of practical cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The numeric range control Scale can be used to resize numeric values.

First, prepare a list of various information and generate fonts.

# font setting.font_size = 12font_family = ['Times','Arial',' Roma'] font_weight = ['bold',' normal'] font_slant = ['italic','roman','normal']

# create fontlabel_font = Font (family=font_family [0], size=font_size, weight=font_weight [0], slant=font_slant [0]) use the font generated above to build a demo object tag: # create a label to display message.label = Label (root, text='ScaleTest', font=label_font, foreground= "# 000000",) label.grid (row=0, column=0, columnspan=4, sticky=E + W) to build Checkbutton controls that toggle underscores and delete lines:

# toggle underline.def toggle_underline (): under_line = label_font.cget ('underline') label_font.config (underline=not under_line) # create check button.ub = Checkbutton (root,text= "Underline", command=toggle_underline) ub.grid (row=1, column=0, columnspan=2) # toggle overstrike.def toggle_overstrike (): over_strike = label_font.cget (' overstrike') label_font.config (overstrike=not over_strike) # create check button.ob = Checkbutton (root,text= "Overstrike" Command=toggle_overstrike) ob.grid (row=1, column=1, columnspan=2)

Build Spinbox controls that adjust font and weight. ‍

# label of readonly spinbox.Label (root, text='Family') .grid (row=2,column=0, sticky=E) def family_changed (): label_font.config (family=fb.get ()) # create a value spinbox.fb = Spinbox (root, values=font_family, wrap=True, state='readonly', command=family_changed) fb.grid (row=2,column= 1, columnspan=2, sticky=W+E)

# label of weight spinbox.Label (root, text='Weight') .grid (row=3,column=0, sticky=E) def weight_changed (): label_font.config (weight=wb.get ()) # create a weight spinbox.wb = Spinbox (root, values=font_weight, wrap=True, state='readonly', command=weight_changed) wb.grid (row=3,column= 1, columnspan=3, sticky=W+E)

So far, it's all explained before, and then there's the protagonist Scale control.

# create a lable of size scale.Label (root, text='Size') .grid (row=4,column=0, sticky=E)

Def scale_changed (value): label_font.config (size=value)

# create font size scale.fs = Scale (root, relief=GROOVE, orient=HORIZONTAL, from_=10, to_=32, resolution=1, command=scale_changed) fs.grid (row=4, column=1, columnspan=3, sticky=W+E)

The function that handles the drag event has an argument to pass the current value of the Scale control. With this parameter, you don't have to get it from the control. This process is used to set the font size, and the result is reflected directly on the label control.

# create a lable of gray scale.Label (root, text='Gray') .grid (row=5,column=0, sticky=E)

Def gray_changed (value): value ='{: 02x} '.format (int (value)) value =' #'+ value+value+value label.config (foreground=value) # create gray scale.cs = Scale (root, relief=GROOVE, orient=HORIZONTAL, from_=0, to_=255, resolution=1, command=gray_changed) cs.grid (row=5, column=1, columnspan=3, sticky=W+E)

The color adjustment process is basically the same as the font size, except that the color is generated using string formatting and merging.
